for the convenient synthesis of InP/ZnSquantumdots (QDs). From these precursors, remarkably long‐term stable stock solutions (>6 months) of P(OLA)3 (OLAH=oleylamine) are generated from which the respective pyrazoles are conveniently recovered. P(OLA)3 acts simultaneously as phosphorus source and reducing agent in the synthesis of highly emitting InP/ZnS core/shell QDs. These QDs are characterized by

groups of one ligand and to the P-apex of the other ligand as confirmed by an X-raycrystalstructure determination and a DFT computational analysis. Reacting the ligand and the Cu(I) complex in an equimolar ratio resulted in a remarkable one-dimensional P-scorpion coordination polymer for which a single crystalX-raystructure could be determined. A detailed analysis of the structural features is presented
presence of tris(3,5 dimethyl-1-pyrazolyl)phosphane in toluene under thermolytic condition afforded a four-coordinated Mn(II)-NHC-phosphane complex, 1 which represents an unprecedented example of Mn(II)-NHC complex having a phosphane unit attached to the abnormal position (C4) of NHC. Compound 1 has been characterized by mass spectrometry, elemental analysis, and 31P NMRspectroscopic analysis. The
